Abstract
"Canino" apricot  (Prunus  armeniaca L.) fruiting trees were sprayed with different bud dormancy breaking compounds on  January  20th at different concentrations.  Dormex (hydrogen cyanamide) was sprayed at 1,2 and 3% eash alone , zinc sulphate at 5% and urea at 6% alone or combined with 3% mineral oil.All Dormex concentrations alone or combined with mineral oil increased floral and vegetative bud opening and increased retained fruits and yield as compared with the untreated trees. Moreover, total indoles and total free amino acids in shoot buds were increased by all treatments compared with the control.The highest values were obtained by using  Dormex at 3% followed by  Dormex at 2% . Also , all experimental treatments increased leaf content of nitrogen(N) , phosphorus(P) and potassium(K) comparing with the control , especially in treatments of Dormex 3% followed by Dormex 3% + mineral oil 3% ; however , urea at 6% alone or mixed by mineral oil 3% did not have reliable effect .The most effective treatment was spraying Dormex at 3% alone , which gave the highest  percentage of opend  floral and vegetative buds and the highest yield (kg/tree) .
